Thirty-five were built at Crewe Works between 1937 and 1948, many having streamlined casing. Ten were set aside for hauling the prestigious ‘Coronation Scot’ between London Euston and Glasgow. �No. 46230 wasn’t one of those, but it was the first of the third batch of locomotives, which consisted of five non-streamlined versions, and went new to Camden in June 1938 as LMS No. 6230.
